Subject: ExternalReference.DocumentHash
Hi Developers, What is a purpose of DocumentHash inside an ExternalReference? a) Cryptography: External Document is encrypted and can be decrypted using DocumentHash value. b) Error correction: Hash code is used to detect errors in transmission and to check that no one has changed the document. In other words, a calculated hash code of a downloaded document should match DocumentHash value. c) Something else?
